Water Softener Safety
For installations in the Commonwealth of Massachusetts:
Installation b y a licensed plumber is required. Plumbing code 248--CMR of the Commonwealth
of Massachusetts must be used for installation.
For installations in the state of California:
You must turn the Salt Efficiency Feature s etting to ON. This may initiate more f requent re-
charges, however, it will operate at 4,000 grains per pound of salt or higher. To turn on the Salt
Efficiency Feature, follow the instructions in the “Salt Efficiency” section of this manual.
Before You Start
See “Location Requirements” section before installing water softener.
Follow the installation instructions carefully. (Failure to install the water softener properly voids the
warranty.)
Before you begin installation, read this entire manual. Then, obtain all the materials and tools you will
need to make the installation.
Check local plumbing and electrical codes.
Use only lead--free solder and flux for all sweat-solder c onnections, as required by federal codes.
Use care when handling the water softener. Do not turn upside down, drop, or set on sharp protrusions.
Avoid installing in direct sunlight. Excessive sun heat may cause distortion or other damage to
non--metallic parts.
